Optical Fiber Rangers

An optical fiber ranger is a fiber tester which functions similar to an optical time domain reflectometer. It is used in fiber network installation, fiber network engineering acquisition and fiber network maintenance. GAOTek offers a variety of optical fiber rangers for detecting fiber fault locations more accurately and quickly for sale to the Unites States, Canada and Globally. Our fiber rangers adopt the OTDR technical principles and integrate powerful analysis software to quickly and accurately detect the location and type of fiber optic cable failure point.

GAOTek Optical Fiber Rangers are lightweight and rugged and offer a cost-effective and efficient tool for technicians in fiber system installation, engineering and maintenance. Some of these devices are multifunctional and come with built-in visual fault locator (VFL) which locates the faults in dead zones..

At GAOTek we strive to offer superior quality products to our valued customers all over the world. Our high quality Optical Fiber Rangers are manufactured using advanced technology and are highly preferred by technical experts because of their portability, usefulness, affordable price, and high performance.

Functions of Optical Fiber Rangers

Fiber Optic Rangers will usually inject the laser pulse into the optical fiber so as to verify and accumulate the reflected light waves throughout the work process. The main function of the Optical Fiber Rangers is to locate areas and types of both bases on a set of pre-determined threshold values and go through the whole length of the fiber under test. They do not exhibit fiber trace or provide any data relating to the fiber and event losses. Known to be highly-performing testing meters, these devices are principally used for the day-to-day maintenance, fault location, and detection of the optical network system.


GAOTek Optical Fiber Rangers are transportable and reliable test devices designed for the industry. They comply with the OTDR technical guidelines and include a strong analysis software, which in turn allows the fiber rangers to precisely and easily detect any fiber fault. A large LCD display and a durable battery which can last for several hours are included in these equipment, which make them ideal tools for field works. GAOTek’s affordable and user-friendly fiber rangers are perfect devices for the fiber cable construction and maintenance.

Applications and Industries

Optical Fiber Rangers are extensively utilized to evaluate the distance of the fibers and identify the fault locations on the fiber links. They can also be used to spot reflective and non-reflective cracks on the fiber systems during an inspection. Fiber rangers are particularly designed for the FTTx network installation and maintenance which are appropriate for WAN, LAN, metro LAN, CATV, among others.
